DBMS_LOB.GET_LENGTH instead of DBMS_LOB.GETLENGTH

INSERT INTO table [(col1, col2, ..., coln)]
AS
SELECT ...;

The correct synthax should be (according to Oracle 10.2 documentation) without AS like that:

INSERT INTO table [(col1, col2, ..., coln)]
SELECT ...;

my_book.isbn
my_book.title
my_book.summary
my_book.author

UPDATE books

In the statement:

UPDATE books
SET page_count
WHERE isbn = my_books (book_index);

change:
SET page_count
to
SET page_count = page_count / 2

The third bullet point (just before section "ROLLBACK behavior with FORALL") talks
about "deletes and inserts". It should be "deletes and updates", as inserts are
covered by bullet point #2.

the Boolean indices collection had no element defined at position 13067.

should be:

the "values of" collection had no element whose value equaled 13067.

Remove entire bullet item.
